Speech-to-Speech is a service for people with speech disabilities. If you have a speech disability and live in the USA, you can now use a free† telephone relay service, available 24 hours a day. This service is similar to the TTY service available to the hearing disabled except that it does not require typing. This service, called Speech-to-Speech (STS), provides communication assistants (CA's) for people with difficulty being understood by the public on the telephone. It is available for business, medical, and personal communication.
